The biggest advantage of free CAD software is its cost: nothing! It may also offer the tools you need, especially free CAD software for beginners, students, hobbyists, or individual contractors. However, businesses small and large may find it doesn’t have enough features.

Free 2D CAD software often has very limited storage space, especially considering the large file formats many CAD users need. It may not be able to view, edit, and manage the file types you need, like DWG and DXF files. And it may have too few seats – often just one.
